Perle Tumbler, conceived by Federico de Majo for Zafferano. The Perle tumbler is ideal for water and other types of drinks. Perle is a collection of glasses, bowls and table accessories that comes from the ancient working method of applying a twist to the glass and breaking it, then completed by hand by the master glassmakers. Perle has become iconic both for its bright colors and for its original look, perfect for bringing liveliness to the table.
